Pause, curse that the wagon is far away from where you want to build, find a soil hill to hollow out for temporary living/storage, designate, designate some more, designate trees for chopping, set up temporary workshops made from wood (masons, carpenters, butcher, tanner, kennels if war dogs are needed immediately). Unpause. Wait. Curse some more that you forgot to turn on mining for everyone. Curse again when you realize a worshop isn't being built because nobody has that skill. Pause when the hill is dug out. Designate stockpiles for furniture, goods, weapons, ammo, food inside, stockpile for wood and stone outside. Create farm plot(s) and kitchen/still/farmers workshop inside next to the plots. Unpause, curse some more when workshop isn't built because nobody has plant processing enabled. Start making 7 beds from the wood that's left, then queue up barrels on repeat. Wonder why no trees have been cut, realize that mining cancels out woodcutting, curse. Build wooden cage for animals, start digging again to get stone to make tables and chairs. Hurriedly start placing beds when you see a dwarf sleeping on the floor. Draft 2 or 3 no skill recruits to fend off some wild animals that are interrupting jobs. Finally destroy the wagon and curse when you realize there were still things inside that don't have a stockpile, or their stockpile is too small.
And that's the easy, relaxing part over with.
